A library of 1H-1,2,3-triazole-tethered ospemifene–isatin and ospemifene–spiroisatin conjugates have been synthesized and evaluated for their anti-proliferative activities against MCF-7 and MDA-MB-231 cell lines. The evaluation studies revealed that compound 11j was the most potent with an IC50 value of 1.56 μM against the MCF-7 cell line. Compounds 11k and 11l also displayed a similar trend, with
已合成了1 H -1,2,3-三唑系泊的欧司哌米芬-伊斯汀和欧司哌米芬-螺旋素共轭物的文库,并评估了它们对MCF-7和MDA-MB-231细胞系的抗增殖活性。评估研究表明,化合物11j对MCF-7细胞系的作用最强,IC 50值为1.56μM。化合物11k和11lER +细胞的有效浓度也比ER-细胞低几倍。SAR研究表明,在以乙基/丙基为间隔基的靛蓝环的C-5和C-7位上具有溴取代基的缀合物具有活性,最有效的化合物比他莫昔芬的效价高约30倍。 MCF-7细胞系。评估结果得到对接研究的进一步支持,合成缀合物的较强结合亲和力归因于其更大的结构体积和对ERα活性位点的更大占有。
